Thats good that your not using wire, I have had wire cages without any place to get off it and my bunnies have developed sore hocks, which are scabs on their heels. I have since bought a hutch with a hide out with hay so they can get off the wire.

Lots of people give their bunnies the whole phone book when the new one comes in and it is perfectly safe. Most bunnies don't actually eat the paper they usually rip it up and chew it. I also give my left over wrapping paper( from opening presents and stuff) wich they love to rip up and make a lovley mess lol.

As for store bought toys I have found most bunnies demolish these, they are called "Flip 'n' Toss" I belive or something along those lines.



Bunnies LOVE to chew apart wicker baskets (without the coating of course)

My bunnies love these



There is also this that they love to throw in the air and toss around


Also cardboard is good and like you said old toilet paper rolls.

As a baby you can give him/ her cheerios like one a day to earn his/her trust. And if he/she gets a little bit of runny poo put a little plain dry oatmeal in a container the runny poo can because by stress. There is a poo that they produce called cecil wich is a wet poo that looks like a bunch of grapes stuck together that is normal and will continue to happen their whole life, it is for them to eat to help digest the food a second time around.

Don't use shavings as bedding as it can cause upper respratory issues.
Rip up news paper (Once he/she is litter trained you could probly add less) . Don't put it down flat without ripping it because it can make their feet blue from the ink.
